# @rollup/plugin-babel changelog
## 5.0.0
_2020-04-27_
### Features
- Added `getBabelOutputPlugin` and `createBabelOutputPluginFactory` exports which can be used to transform generated code
- Added `skipPreflightCheck` option. The plugin performs some extra checks to see if the passed configuration is correct and matching its expectations. This comes with some runtime overhead and can slow down builds. If you know what you are doing and you are confident that you have configured things correctly you can disable those checks with this option.
- Published as `@rollup/plugin-babel`
### Updates
- Default export exported as `getBabelInputPlugin` for symmetry with `getBabelOutputPlugin`
### Breaking Changes
- Minimum compatible Rollup version is 1.2.0
- Minimum supported Node version is 10.0.0
- `.custom` factory is now available as separate `createBabelInputPluginFactory` export
- Removed `externalHelpers` & `runtimeHelpers` options. There is now a single `babelHelpers` option which can take one of `'bundled'`, `'inline'`, `'runtime'` and `'external'` as a value. The default is `'bundled'` which matches 4.x behavior, but it is recommended to configure this option explicitly.
## 4.3.2
- Fixed usage with `externalHelpers: true` option
## 4.3.1
- Add `.js` extension to the virtual babel helpers file (only matters when using `preserveModules` option in rollup)
## 4.3.0
- Added `.custom` builder.
- Fail build when a plugin tries to add non existent babel helper
## 4.2.0
Allow `rollup@1` as peer dependency.
## 4.1.0
- Fixed "preflight check" for ignored files.
- Return `null` when no transformation has been done (fixing source maps for this case)
## 4.0.3
Fixed fallback class transform in "preflight check".
## 4.0.2
Fixed `rollup` peer dependency.
## 4.0.0
Babel 7 compatible! (dropped Babel 6 compatibility though).
Additionally:
- Internal preflight checks are created now per plugin instance, so using 2 instances of rollup-plugin-babel (i.e. targeting 2 different set of files with include/exclude options) shouldn't conflict with each other
- Transpiling by default only what Babel transpiles - files with those extensions: .js, .jsx, .es6, .es, .mjs. You can customize this with new `extensions` option. This also fixes long standing issue with rollup-plugin-babel trying to transform JSON files.
## 3.0.3
- Drop babel7 support. Use 4.0.0-beta if you use babel 7
- Use "module" in addition to "jsnext:main" ([#150](https://github.com/rollup/rollup-plugin-babel/issues/150))
- Remove unused babel helpers namespace declaration & expression ([#164](https://github.com/rollup/rollup-plugin-babel/issues/164))
## 3.0.2
- Fix regression with Babel 6 ([#158](https://github.com/rollup/rollup-plugin-babel/issues/158))
## 3.0.1
- Wasn't working, fix bug with transform (not using es2015-classes for preflight check)
## 3.0.0
- Drop Node 0.10/0.12 (Use native `Object.assign`)
- Change `babel-core` to be a peerDependency
- Support `babel-core` v7 as well as a peerDep (no changes necessary)
## 2.7.1
- Prevent erroneous warnings about duplicated runtime helpers ([#105](https://github.com/rollup/rollup-plugin-babel/issues/105))
- Ignore `ignore` option in preflight check ([#102](https://github.com/rollup/rollup-plugin-babel/issues/102))
- Allow custom `moduleName` with `runtime-helpers` ([#95](https://github.com/rollup/rollup-plugin-babel/issues/95))
## 2.7.0
- Add `externalHelpersWhitelist` option ([#92](https://github.com/rollup/rollup-plugin-babel/pull/92))
- Ignore `only` option during preflight checks ([#98](https://github.com/rollup/rollup-plugin-babel/issues/98))
- Use `options.onwarn` if available ([#84](https://github.com/rollup/rollup-plugin-babel/issues/84))
- Update documentation and dependencies
## 2.6.1
- Return a `name`
## 2.6.0
- Use `\0` convention for helper module ID ([#64](https://github.com/rollup/rollup-plugin-babel/issues/64))
## 2.5.1
- Don't mutate `options.plugins` ([#47](https://github.com/rollup/rollup-plugin-babel/issues/47))
## 2.5.0
- Import `babelHelpers` rather than injecting them allows `transform` function to be pure ([#rollup/658](https://github.com/rollup/rollup/pull/658#issuecomment-223876824))
## 2.4.0
- Add `externalHelpers` option ([#41](https://github.com/rollup/rollup-plugin-babel/pull/41))
## 2.3.9
- Do not rename Babel helpers ([#34](https://github.com/rollup/rollup-plugin-babel/pull/34))
## 2.3.8
- Create new version to (hopefully) solve bizarre CI issue
## 2.3.7
- Be less clever about renaming Babel helpers ([#19](https://github.com/rollup/rollup-plugin-babel/issues/19))
## 2.3.6
- Fix cache misses in preflight check ([#29](https://github.com/rollup/rollup-plugin-babel/pull/29))
## 2.3.5
- Use class transformer local to plugin, not project being built
## 2.3.4
- Ensure class transformer is present for preflight check, and only run check once per directory ([#23](https://github.com/rollup/rollup-plugin-babel/issues/23))
## 2.3.3
- Fix helper renaming ([#22](https://github.com/rollup/rollup-plugin-babel/issues/22))
## 2.3.1-2
- Include correct files in npm package
## 2.3.0
- Allow `transform-runtime` Babel plugin, if combined with `runtimeHelpers: true` option ([#17](https://github.com/rollup/rollup-plugin-babel/issues/17))
- More permissive handling of helpers only warn if inline helpers are duplicated
- Handle plugins that change export patterns ([#18](https://github.com/rollup/rollup-plugin-babel/issues/18))
## 2.2.0
- Preflight checks are run per-file, to avoid configuration snafus ([#16](https://github.com/rollup/rollup-plugin-babel/issues/16))
## 2.1.0
- Generate sourcemaps by default
## 2.0.1
- Use object-assign ponyfill
- Add travis support

# @rollup/plugin-babel
🍣 A Rollup plugin for seamless integration between Rollup and Babel.
## Why?
If you're using Babel to transpile your ES6/7 code and Rollup to generate a standalone bundle, you have a couple of options:
- run the code through Babel first, being careful to exclude the module transformer, or
- run the code through Rollup first, and _then_ pass it to Babel.
Both approaches have disadvantages in the first case, on top of the additional configuration complexity, you may end up with Babel's helpers (like `classCallCheck`) repeated throughout your code (once for each module where the helpers are used). In the second case, transpiling is likely to be slower, because transpiling a large bundle is much more work for Babel than transpiling a set of small files.
Either way, you have to worry about a place to put the intermediate files, and getting sourcemaps to behave becomes a royal pain.
Using Rollup with `@rollup/plugin-babel` makes the process far easier.
## Requirements
This plugin requires an [LTS](https://github.com/nodejs/Release) Node version (v10.0.0+) and Rollup v1.20.0+.
## Install
```bash
npm install @rollup/plugin-babel --save-dev
```
## Usage
Create a `rollup.config.js` [configuration file](https://www.rollupjs.org/guide/en/#configuration-files) and import the plugin:
```js
import { babel } from '@rollup/plugin-babel';
const config = {
input: 'src/index.js',
output: {
dir: 'output',
format: 'esm'
},
plugins: [babel({ babelHelpers: 'bundled' })]
};
export default config;
```
Then call `rollup` either via the [CLI](https://www.rollupjs.org/guide/en/#command-line-reference) or the [API](https://www.rollupjs.org/guide/en/#javascript-api).
### Using With `@rollup/plugin-commonjs`
When using `@rollup/plugin-babel` with `@rollup/plugin-commonjs` in the same Rollup configuration, it's important to note that `@rollup/plugin-commonjs` _must_ be placed before this plugin in the `plugins` array for the two to work together properly. e.g.
```js
import { babel } from '@rollup/plugin-babel';
import commonjs from '@rollup/plugin-commonjs';
const config = {
...
plugins: [
commonjs(),
babel({ babelHelpers: 'bundled' })
],
};
```
## Options
This plugin respects Babel [configuration files](https://babeljs.io/docs/en/configuration) by default and they are generally the best place to put your configuration.
You can also run Babel on the generated chunks instead of the input files. Even though this is slower, it is the only way to transpile Rollup's auto-generated wrapper code to lower compatibility targets than ES5, see [Running Babel on the generated code](#running-babel-on-the-generated-code) for details.
All options are as per the [Babel documentation](https://babeljs.io/docs/en/options), plus the following:
### `exclude`
Type: `String | RegExp | Array[...String|RegExp]`<br>
A [minimatch pattern](https://github.com/isaacs/minimatch), or array of patterns, which specifies the files in the build the plugin should _ignore_. When relying on Babel configuration files you can only exclude additional files with this option, you cannot override what you have configured for Babel itself.
### `include`
Type: `String | RegExp | Array[...String|RegExp]`<br>
A [minimatch pattern](https://github.com/isaacs/minimatch), or array of patterns, which specifies the files in the build the plugin should operate on. When relying on Babel configuration files you cannot include files already excluded there.
### `filter`
Type: (id: string) => boolean<br>
Custom [filter function](https://github.com/rollup/plugins/tree/master/packages/pluginutils#createfilter) can be used to determine whether or not certain modules should be operated upon.
Usage:
```js
import { createFilter } from '@rollup/pluginutils';
const include = 'include/**.js';
const exclude = 'exclude/**.js';
const filter = createFilter(include, exclude, {});
```
### `extensions`
Type: `Array[...String]`<br>
Default: `['.js', '.jsx', '.es6', '.es', '.mjs']`
An array of file extensions that Babel should transpile. If you want to transpile TypeScript files with this plugin it's essential to include `.ts` and `.tsx` in this option.
### `babelHelpers`
Type: `'bundled' | 'runtime' | 'inline' | 'external'`<br>
Default: `'bundled'`
It is recommended to configure this option explicitly (even if with its default value) so an informed decision is taken on how those babel helpers are inserted into the code.
We recommend to follow these guidelines to determine the most appropriate value for your project:
- `'runtime'` - you should use this especially when building libraries with Rollup. It has to be used in combination with `@babel/plugin-transform-runtime` and you should also specify `@babel/runtime` as dependency of your package. Don't forget to tell Rollup to treat the helpers imported from within the `@babel/runtime` module as external dependencies when bundling for `cjs` & `es` formats. This can be accomplished via regex (`external: [/@babel\/runtime/]`) or a function (`external: id => id.includes('@babel/runtime')`). It's important to not only specify `external: ['@babel/runtime']` since the helpers are imported from nested paths (e.g `@babel/runtime/helpers/get`) and [Rollup will only exclude modules that match strings exactly](https://rollupjs.org/guide/en/#peer-dependencies).
- `'bundled'` - you should use this if you want your resulting bundle to contain those helpers (at most one copy of each). Useful especially if you bundle an application code.
- `'external'` - use this only if you know what you are doing. It will reference helpers on **global** `babelHelpers` object. Used in combination with `@babel/plugin-external-helpers`.
- `'inline'` - this is not recommended. Helpers will be inserted in each file using this option. This can cause serious code duplication. This is the default Babel behavior as Babel operates on isolated files - however, as Rollup is a bundler and is project-aware (and therefore likely operating across multiple input files), the default of this plugin is `"bundled"`.
### `skipPreflightCheck`
Type: `Boolean`<br>
Default: `false`
Before transpiling your input files this plugin also transpile a short piece of code **for each** input file. This is used to validate some misconfiguration errors, but for sufficiently big projects it can slow your build times so if you are confident about your configuration then you might disable those checks with this option.
### External dependencies
Ideally, you should only be transforming your source code, rather than running all of your external dependencies through Babel (to ignore external dependencies from being handled by this plugin you might use `exclude: 'node_modules/**'` option). If you have a dependency that exposes untranspiled ES6 source code that doesn't run in your target environment, then you may need to break this rule, but it often causes problems with unusual `.babelrc` files or mismatched versions of Babel.
We encourage library authors not to distribute code that uses untranspiled ES6 features (other than modules) for this reason. Consumers of your library should _not_ have to transpile your ES6 code, any more than they should have to transpile your CoffeeScript, ClojureScript or TypeScript.
Use `babelrc: false` to prevent Babel from using local (i.e. to your external dependencies) `.babelrc` files, relying instead on the configuration you pass in.
### Helpers
In some cases Babel uses _helpers_ to avoid repeating chunks of code  for example, if you use the `class` keyword, it will use a `classCallCheck` function to ensure that the class is instantiated correctly.
By default, those helpers will be inserted at the top of the file being transformed, which can lead to duplication. This rollup plugin automatically deduplicates those helpers, keeping only one copy of each one used in the output bundle. Rollup will combine the helpers in a single block at the top of your bundle.
You can customize how those helpers are being inserted into the transformed file with [`babelHelpers`](#babelhelpers) option.
### Modules
This is not needed since Babel 7 - it knows automatically that Rollup understands ES modules & that it shouldn't use any module transform with it. Unless you forcefully include a module transform in your Babel configuration.
If you have been pointed to this section by an error thrown by this plugin, please check your Babel configuration files and disable any module transforms when running Rollup builds.
## Running Babel on the generated code
You can run `@rollup/plugin-babel` on the output files instead of the input files by using `getBabelOutputPlugin(...)`. This can be used to perform code transformations on the resulting chunks and is the only way to transform Rollup's auto-generated code. By default, the plugin will be applied to all outputs:
```js
// rollup.config.js
import { getBabelOutputPlugin } from '@rollup/plugin-babel';
export default {
input: 'main.js',
plugins: [
getBabelOutputPlugin({
presets: ['@babel/preset-env']
})
],
output: [
{ file: 'bundle.cjs.js', format: 'cjs' },
{ file: 'bundle.esm.js', format: 'esm' }
]
};
```
If you only want to apply it to specific outputs, you can use it as an output plugin (requires at least Rollup v1.27.0):
```js
// rollup.config.js
import { getBabelOutputPlugin } from '@rollup/plugin-babel';
export default {
input: 'main.js',
output: [
{ file: 'bundle.js', format: 'esm' },
{
file: 'bundle.es5.js',
format: 'esm',
plugins: [getBabelOutputPlugin({ presets: ['@babel/preset-env'] })]
}
]
};
```
The `include`, `exclude` and `extensions` options are ignored when the when using `getBabelOutputPlugin` and `createBabelOutputPluginFactory` will produce warnings, and there are a few more points to note that users should be aware of.
You can also run the plugin twice on the code, once when processing the input files to transpile special syntax to JavaScript and once on the output to transpile to a lower compatibility target:
```js
// rollup.config.js
import babel, { getBabelOutputPlugin } from '@rollup/plugin-babel';
export default {
input: 'main.js',
plugins: [babel({ presets: ['@babel/preset-react'] })],
output: [
{
file: 'bundle.js',
format: 'esm',
plugins: [getBabelOutputPlugin({ presets: ['@babel/preset-env'] })]
}
]
};
```
### Babel configuration files
Unlike the regular `babel` plugin, `getBabelOutputPlugin(...)` will **not** automatically search for [Babel configuration files](https://babeljs.io/docs/en/config-files). Besides passing in Babel options directly, however, you can specify a configuration file manually via Babel's [`configFile`](https://babeljs.io/docs/en/options#configfile) option:
```js
getBabelOutputPlugin({
configFile: path.resolve(__dirname, 'babel.config.js')
});
```
### Using formats other than ES modules or CommonJS
As `getBabelOutputPlugin(...)` will run _after_ Rollup has done all its transformations, it needs to make sure it preserves the semantics of Rollup's output format. This is especially important for Babel plugins that add, modify or remove imports or exports, but also for other transformations that add new variables as they can accidentally become global variables depending on the format. Therefore it is recommended that for formats other than `esm` or `cjs`, you set Rollup to use the `esm` output format and let Babel handle the transformation to another format, e.g. via
```
presets: [['@babel/preset-env', { modules: 'umd' }], ...]
```
to create a UMD/IIFE compatible output. If you want to use `getBabelOutputPlugin(...)` with other formats, you need to specify `allowAllFormats: true` as plugin option:
```js
rollup.rollup({...})
.then(bundle => bundle.generate({
format: 'iife',
plugins: [getBabelOutputPlugin({
allowAllFormats: true,
// ...
})]
}))
```
### Injected helpers
By default, helpers e.g. when transpiling classes will be inserted at the top of each chunk. In contrast to when applying this plugin on the input files, helpers will not be deduplicated across chunks.
Alternatively, you can use imported runtime helpers by adding the `@babel/transform-runtime` plugin. This will make `@babel/runtime` an external dependency of your project, see [@babel/plugin-transform-runtime](https://babeljs.io/docs/en/babel-plugin-transform-runtime) for details.
Note that this will only work for `esm` and `cjs` formats, and you need to make sure to set the `useESModules` option of `@babel/plugin-transform-runtime` to `true` if you create ESM output:
```js
rollup.rollup({...})
.then(bundle => bundle.generate({
format: 'esm',
plugins: [getBabelOutputPlugin({
presets: ['@babel/preset-env'],
plugins: [['@babel/plugin-transform-runtime', { useESModules: true }]]
})]
}))
```
```js
// input
export default class Foo {}
// output
import _classCallCheck from '@babel/runtime/helpers/esm/classCallCheck';
var Foo = function Foo() {
_classCallCheck(this, Foo);
};
export default Foo;
```
And for CommonJS:
```js
rollup.rollup({...})
.then(bundle => bundle.generate({
format: 'cjs',
plugins: [getBabelOutputPlugin({
presets: ['@babel/preset-env'],
plugins: [['@babel/plugin-transform-runtime', { useESModules: false }]]
})]
}))
```
```js
// input
export default class Foo {}
// output
('use strict');
var _classCallCheck = require('@babel/runtime/helpers/classCallCheck');
var Foo = function Foo() {
_classCallCheck(this, Foo);
};
module.exports = Foo;
```
Another option is to use `@babel/plugin-external-helpers`, which will reference the global `babelHelpers` object. It is your responsibility to make sure this global variable exists.
## Custom plugin builder
`@rollup/plugin-babel` exposes a plugin-builder utility that allows users to add custom handling of Babel's configuration for each file that it processes.
`createBabelInputPluginFactory` accepts a callback that will be called with the loader's instance of `babel` so that tooling can ensure that it using exactly the same `@babel/core` instance as the loader itself.
It's main purpose is to allow other tools for configuration of transpilation without forcing people to add extra configuration but still allow for using their own babelrc / babel config files.
### Example
```js
import { createBabelInputPluginFactory } from '@rollup/plugin-babel';
export default createBabelInputPluginFactory((babelCore) => {
function myPlugin() {
return {
visitor: {}
};
}
return {
// Passed the plugin options.
options({ opt1, opt2, ...pluginOptions }) {
return {
// Pull out any custom options that the plugin might have.
customOptions: { opt1, opt2 },
// Pass the options back with the two custom options removed.
pluginOptions
};
},
config(cfg /* Passed Babel's 'PartialConfig' object. */, { code, customOptions }) {
if (cfg.hasFilesystemConfig()) {
// Use the normal config
return cfg.options;
}
return {
...cfg.options,
plugins: [
...(cfg.options.plugins || []),
// Include a custom plugin in the options.
myPlugin
]
};
},
result(result, { code, customOptions, config, transformOptions }) {
return {
...result,
code: result.code + '\n// Generated by some custom plugin'
};
}
};
});
```

# @rollup/plugin-node-resolve
🍣 A Rollup plugin which locates modules using the [Node resolution algorithm](https://nodejs.org/api/modules.html#modules_all_together), for using third party modules in `node_modules`
## Requirements
This plugin requires an [LTS](https://github.com/nodejs/Release) Node version (v8.0.0+) and Rollup v1.20.0+.
## Install
Using npm:
```console
npm install @rollup/plugin-node-resolve --save-dev
```
## Usage
Create a `rollup.config.js` [configuration file](https://www.rollupjs.org/guide/en/#configuration-files) and import the plugin:
```js
import { nodeResolve } from '@rollup/plugin-node-resolve';
export default {
input: 'src/index.js',
output: {
dir: 'output',
format: 'cjs'
},
plugins: [nodeResolve()]
};
```
Then call `rollup` either via the [CLI](https://www.rollupjs.org/guide/en/#command-line-reference) or the [API](https://www.rollupjs.org/guide/en/#javascript-api).
## Package entrypoints
This plugin supports the package entrypoints feature from node js, specified in the `exports` or `imports` field of a package. Check the [official documentation](https://nodejs.org/api/packages.html#packages_package_entry_points) for more information on how this works. This is the default behavior. In the abscence of these fields, the fields in `mainFields` will be the ones to be used.
## Options
### `exportConditions`
Type: `Array[...String]`<br>
Default: `[]`
Additional conditions of the package.json exports field to match when resolving modules. By default, this plugin looks for the `['default', 'module', 'import']` conditions when resolving imports.
When using `@rollup/plugin-commonjs` v16 or higher, this plugin will use the `['default', 'module', 'require']` conditions when resolving require statements.
Setting this option will add extra conditions on top of the default conditions. See https://nodejs.org/api/packages.html#packages_conditional_exports for more information.
### `browser`
Type: `Boolean`<br>
Default: `false`
If `true`, instructs the plugin to use the `"browser"` property in `package.json` files to specify alternative files to load for bundling. This is useful when bundling for a browser environment. Alternatively, a value of `'browser'` can be added to the `mainFields` option. If `false`, any `"browser"` properties in package files will be ignored. This option takes precedence over `mainFields`.
> This option does not work when a package is using [package entrypoints](https://nodejs.org/api/packages.html#packages_package_entry_points)
### `moduleDirectories`
Type: `Array[...String]`<br>
Default: `['node_modules']`
One or more directories in which to recursively look for modules.
### `dedupe`
Type: `Array[...String]`<br>
Default: `[]`
An `Array` of modules names, which instructs the plugin to force resolving for the specified modules to the root `node_modules`. Helps to prevent bundling the same package multiple times if package is imported from dependencies.
```js
dedupe: ['my-package', '@namespace/my-package'];
```
This will deduplicate bare imports such as:
```js
import 'my-package';
import '@namespace/my-package';
```
And it will deduplicate deep imports such as:
```js
import 'my-package/foo.js';
import '@namespace/my-package/bar.js';
```
### `extensions`
Type: `Array[...String]`<br>
Default: `['.mjs', '.js', '.json', '.node']`
Specifies the extensions of files that the plugin will operate on.
### `jail`
Type: `String`<br>
Default: `'/'`
Locks the module search within specified path (e.g. chroot). Modules defined outside this path will be ignored by this plugin.
### `mainFields`
Type: `Array[...String]`<br>
Default: `['module', 'main']`<br>
Valid values: `['browser', 'jsnext:main', 'module', 'main']`
Specifies the properties to scan within a `package.json`, used to determine the bundle entry point. The order of property names is significant, as the first-found property is used as the resolved entry point. If the array contains `'browser'`, key/values specified in the `package.json` `browser` property will be used.
### `preferBuiltins`
Type: `Boolean`<br>
Default: `true` (with warnings if a builtin module is used over a local version. Set to `true` to disable warning.)
If `true`, the plugin will prefer built-in modules (e.g. `fs`, `path`). If `false`, the plugin will look for locally installed modules of the same name.
### `modulesOnly`
Type: `Boolean`<br>
Default: `false`
If `true`, inspect resolved files to assert that they are ES2015 modules.
### `resolveOnly`
Type: `Array[...String|RegExp]`<br>
Default: `null`
An `Array` which instructs the plugin to limit module resolution to those whose names match patterns in the array. _Note: Modules not matching any patterns will be marked as external._
Example: `resolveOnly: ['batman', /^@batcave\/.*$/]`
### `rootDir`
Type: `String`<br>
Default: `process.cwd()`
Specifies the root directory from which to resolve modules. Typically used when resolving entry-point imports, and when resolving deduplicated modules. Useful when executing rollup in a package of a mono-repository.
```
// Set the root directory to be the parent folder
rootDir: path.join(process.cwd(), '..')
```
## `ignoreSideEffectsForRoot`
If you use the `sideEffects` property in the package.json, by default this is respected for files in the root package. Set to `true` to ignore the `sideEffects` configuration for the root package.
## Preserving symlinks
This plugin honours the rollup [`preserveSymlinks`](https://rollupjs.org/guide/en/#preservesymlinks) option.
## Using with @rollup/plugin-commonjs
Since most packages in your node_modules folder are probably legacy CommonJS rather than JavaScript modules, you may need to use [@rollup/plugin-commonjs](https://github.com/rollup/plugins/tree/master/packages/commonjs):
```js
// rollup.config.js
import { nodeResolve } from '@rollup/plugin-node-resolve';
import commonjs from '@rollup/plugin-commonjs';
export default {
input: 'main.js',
output: {
file: 'bundle.js',
format: 'iife',
name: 'MyModule'
},
plugins: [nodeResolve(), commonjs()]
};
```
## Resolving Built-Ins (like `fs`)
By default this plugin will prefer built-ins over local modules, marking them as external.
See [`preferBuiltins`](#preferbuiltins).
To provide stubbed versions of Node built-ins, use a plugin like [rollup-plugin-node-polyfills](https://github.com/ionic-team/rollup-plugin-node-polyfills) and set `preferBuiltins` to `false`. e.g.
```js
import { nodeResolve } from '@rollup/plugin-node-resolve';
import nodePolyfills from 'rollup-plugin-node-polyfills';
export default ({
input: ...,
plugins: [
nodePolyfills(),
nodeResolve({ preferBuiltins: false })
],
external: builtins,
output: ...
})
```
## Resolving require statements
According to [NodeJS module resolution](https://nodejs.org/api/packages.html#packages_package_entry_points) `require` statements should resolve using the `require` condition in the package exports field, while es modules should use the `import` condition.
The node resolve plugin uses `import` by default, you can opt into using the `require` semantics by passing an extra option to the resolve function:
```js
this.resolve(importee, importer, {
skipSelf: true,
custom: { 'node-resolve': { isRequire: true } }
});
```

# @rollup/plugin-replace
🍣 A Rollup plugin which replaces targeted strings in files while bundling.
## Requirements
This plugin requires an [LTS](https://github.com/nodejs/Release) Node version (v8.0.0+) and Rollup v1.20.0+.
## Install
Using npm:
```console
npm install @rollup/plugin-replace --save-dev
```
## Usage
Create a `rollup.config.js` [configuration file](https://www.rollupjs.org/guide/en/#configuration-files) and import the plugin:
```js
import replace from '@rollup/plugin-replace';
export default {
input: 'src/index.js',
output: {
dir: 'output',
format: 'cjs'
},
plugins: [
replace({
'process.env.NODE_ENV': JSON.stringify('production'),
__buildDate__: () => JSON.stringify(new Date()),
__buildVersion: 15
})
]
};
```
Then call `rollup` either via the [CLI](https://www.rollupjs.org/guide/en/#command-line-reference) or the [API](https://www.rollupjs.org/guide/en/#javascript-api).
The configuration above will replace every instance of `process.env.NODE_ENV` with `"production"` and `__buildDate__` with the result of the given function in any file included in the build.
_Note: Values must be either primitives (e.g. string, number) or `function` that returns a string. For complex values, use `JSON.stringify`. To replace a target with a value that will be evaluated as a string, set the value to a quoted string (e.g. `"test"`) or use `JSON.stringify` to preprocess the target string safely._
Typically, `@rollup/plugin-replace` should be placed in `plugins` _before_ other plugins so that they may apply optimizations, such as dead code removal.
## Options
In addition to the properties and values specified for replacement, users may also specify the options below.
### `delimiters`
Type: `Array[...String, String]`<br>
Default: `['\b', '\b']`
Specifies the boundaries around which strings will be replaced. By default, delimiters are [word boundaries](https://www.regular-expressions.info/wordboundaries.html). See [Word Boundaries](#word-boundaries) below for more information.
### `preventAssignment`
Type: `Boolean`<br>
Default: `false`
Prevents replacing strings where they are followed by a single equals sign. For example, where the plugin is called as follows:
```js
replace({
values: {
'process.env.DEBUG': 'false'
}
});
```
Observe the following code:
```js
// Input
process.env.DEBUG = false;
if (process.env.DEBUG == true) {
//
}
// Without `preventAssignment`
false = false; // this throws an error because false cannot be assigned to
if (false == true) {
//
}
// With `preventAssignment`
process.env.DEBUG = false;
if (false == true) {
//
}
```
### `exclude`
Type: `String` | `Array[...String]`<br>
Default: `null`
A [minimatch pattern](https://github.com/isaacs/minimatch), or array of patterns, which specifies the files in the build the plugin should _ignore_. By default no files are ignored.
### `include`
Type: `String` | `Array[...String]`<br>
Default: `null`
A [minimatch pattern](https://github.com/isaacs/minimatch), or array of patterns, which specifies the files in the build the plugin should operate on. By default all files are targeted.
### `values`
Type: `{ [key: String]: Replacement }`, where `Replacement` is either a string or a `function` that returns a string.
Default: `{}`
To avoid mixing replacement strings with the other options, you can specify replacements in the `values` option. For example, the following signature:
```js
replace({
include: ['src/**/*.js'],
changed: 'replaced'
});
```
Can be replaced with:
```js
replace({
include: ['src/**/*.js'],
values: {
changed: 'replaced'
}
});
```
## Word Boundaries
By default, values will only match if they are surrounded by _word boundaries_.
Consider the following options and build file:
```js
module.exports = {
...
plugins: [replace({ changed: 'replaced' })]
};
```
```js
// file.js
console.log('changed');
console.log('unchanged');
```
The result would be:
```js
// file.js
console.log('replaced');
console.log('unchanged');
```
To ignore word boundaries and replace every instance of the string, wherever it may be, specify empty strings as delimiters:
```js
export default {
...
plugins: [
replace({
changed: 'replaced',
delimiters: ['', '']
})
]
};
```

# @rollup/pluginutils
A set of utility functions commonly used by 🍣 Rollup plugins.
## Requirements
This plugin requires an [LTS](https://github.com/nodejs/Release) Node version (v8.0.0+) and Rollup v1.20.0+.
## Install
Using npm:
```console
npm install @rollup/pluginutils --save-dev
```
## Usage
```js
import utils from '@rollup/pluginutils';
//...
```
## API
Available utility functions are listed below:
_Note: Parameter names immediately followed by a `?` indicate that the parameter is optional._
### addExtension
Adds an extension to a module ID if one does not exist.
Parameters: `(filename: String, ext?: String)`<br>
Returns: `String`
```js
import { addExtension } from '@rollup/pluginutils';
export default function myPlugin(options = {}) {
return {
resolveId(code, id) {
// only adds an extension if there isn't one already
id = addExtension(id); // `foo` -> `foo.js`, `foo.js -> foo.js`
id = addExtension(id, '.myext'); // `foo` -> `foo.myext`, `foo.js -> `foo.js`
}
};
}
```
### attachScopes
Attaches `Scope` objects to the relevant nodes of an AST. Each `Scope` object has a `scope.contains(name)` method that returns `true` if a given name is defined in the current scope or a parent scope.
Parameters: `(ast: Node, propertyName?: String)`<br>
Returns: `Object`
See [rollup-plugin-inject](https://github.com/rollup/rollup-plugin-inject) or [rollup-plugin-commonjs](https://github.com/rollup/rollup-plugin-commonjs) for an example of usage.
```js
import { attachScopes } from '@rollup/pluginutils';
import { walk } from 'estree-walker';
export default function myPlugin(options = {}) {
return {
transform(code) {
const ast = this.parse(code);
let scope = attachScopes(ast, 'scope');
walk(ast, {
enter(node) {
if (node.scope) scope = node.scope;
if (!scope.contains('foo')) {
// `foo` is not defined, so if we encounter it,
// we assume it's a global
}
},
leave(node) {
if (node.scope) scope = scope.parent;
}
});
}
};
}
```
### createFilter
Constructs a filter function which can be used to determine whether or not certain modules should be operated upon.
Parameters: `(include?: <minmatch>, exclude?: <minmatch>, options?: Object)`<br>
Returns: `String`
#### `include` and `exclude`
Type: `String | RegExp | Array[...String|RegExp]`<br>
A valid [`minimatch`](https://www.npmjs.com/package/minimatch) pattern, or array of patterns. If `options.include` is omitted or has zero length, filter will return `true` by default. Otherwise, an ID must match one or more of the `minimatch` patterns, and must not match any of the `options.exclude` patterns.
#### `options`
##### `resolve`
Type: `String | Boolean | null`
Optionally resolves the patterns against a directory other than `process.cwd()`. If a `String` is specified, then the value will be used as the base directory. Relative paths will be resolved against `process.cwd()` first. If `false`, then the patterns will not be resolved against any directory. This can be useful if you want to create a filter for virtual module names.
#### Usage
```js
import { createFilter } from '@rollup/pluginutils';
export default function myPlugin(options = {}) {
// assume that the myPlugin accepts options of `options.include` and `options.exclude`
var filter = createFilter(options.include, options.exclude, {
resolve: '/my/base/dir'
});
return {
transform(code, id) {
if (!filter(id)) return;
// proceed with the transformation...
}
};
}
```
### dataToEsm
Transforms objects into tree-shakable ES Module imports.
Parameters: `(data: Object)`<br>
Returns: `String`
#### `data`
Type: `Object`
An object to transform into an ES module.
#### Usage
```js
import { dataToEsm } from '@rollup/pluginutils';
const esModuleSource = dataToEsm(
{
custom: 'data',
to: ['treeshake']
},
{
compact: false,
indent: '\t',
preferConst: false,
objectShorthand: false,
namedExports: true
}
);
/*
Outputs the string ES module source:
export const custom = 'data';
export const to = ['treeshake'];
export default { custom, to };
*/
```
### extractAssignedNames
Extracts the names of all assignment targets based upon specified patterns.
Parameters: `(param: Node)`<br>
Returns: `Array[...String]`
#### `param`
Type: `Node`
An `acorn` AST Node.
#### Usage
```js
import { extractAssignedNames } from '@rollup/pluginutils';
import { walk } from 'estree-walker';
export default function myPlugin(options = {}) {
return {
transform(code) {
const ast = this.parse(code);
walk(ast, {
enter(node) {
if (node.type === 'VariableDeclarator') {
const declaredNames = extractAssignedNames(node.id);
// do something with the declared names
// e.g. for `const {x, y: z} = ... => declaredNames = ['x', 'z']
}
}
});
}
};
}
```
### makeLegalIdentifier
Constructs a bundle-safe identifier from a `String`.
Parameters: `(str: String)`<br>
Returns: `String`
#### Usage
```js
import { makeLegalIdentifier } from '@rollup/pluginutils';
makeLegalIdentifier('foo-bar'); // 'foo_bar'
makeLegalIdentifier('typeof'); // '_typeof'
```

// Type definitions for ESTree AST specification
// Project: https://github.com/estree/estree
// Definitions by: RReverser <https://github.com/RReverser>
// Definitions: https://github.com/DefinitelyTyped/DefinitelyTyped
// This definition file follows a somewhat unusual format. ESTree allows
// runtime type checks based on the `type` parameter. In order to explain this
// to typescript we want to use discriminated union types:
// https://github.com/Microsoft/TypeScript/pull/9163
//
// For ESTree this is a bit tricky because the high level interfaces like
// Node or Function are pulling double duty. We want to pass common fields down
// to the interfaces that extend them (like Identifier or
// ArrowFunctionExpression), but you can't extend a type union or enforce
// common fields on them. So we've split the high level interfaces into two
// types, a base type which passes down inhereted fields, and a type union of
// all types which extend the base type. Only the type union is exported, and
// the union is how other types refer to the collection of inheriting types.
//
// This makes the definitions file here somewhat more difficult to maintain,
// but it has the notable advantage of making ESTree much easier to use as
// an end user.
